A quasi -experimental one-group pre-test post-test research design was conducted among 92 adolescent girls studying in class XII at BSF Senior Secondary Schools in East Khasi Hills, Meghalaya using total census enumeration sampling technique. The data were collected using structured questionnaire to assess the knowledge level of polycystic ovarian syndrome (PCOS) before and after the administration of the Information Booklet regarding polycystic ovarian syndrome (PCOS). Analysis of the collected data was done by using descriptive and inferential statistics. The findings of the study revealed that prior to the intervention, only 22 adolescent girls (23.9%) had good knowledge of polycystic ovarian syndrome, 46 (50%) had average knowledge, and 24 (26.1%) had poor knowledge. After the intervention, 68 girls (73.9%) demonstrated good knowledge, 19 (20.7%) had average knowledge, and just 5 (5.4%) had poor knowledge. The mean ± SD scores were 18.43 ± 4.53 for the pre-test and 23.28 ± 3.76 for the post-test, with a mean difference of 4.85. The obtained t-value was -10.324 with 91 degrees of freedom, which was statistically significant at p < 0.001 using a paired t-test. This indicates that the Information Booklet effectively increased knowledge about polycystic ovarian syndrome (PCOS). Furthermore, the study also found that there was a significant association between pre-test knowledge scores and selected demographic variables such as age, religion, stream, age of menarche, family history of PCOS, and previous information about PCOS at a significance level of p ≤ 0.05.

Conclusion: In conclusion, the Information Booklet was effective in enhancing knowledge about PCOS among adolescent girls, as evidenced by the significant increase in mean post-test knowledge scores compared to pre-test scores across all measured areas.
